The Black Death subsided in the Russian Steppe in 1351. Bad hygienic conditions in Europe helped the epidemic spread. European lifestyle also changed greatly during and after the disease. As the Black Plague

seeing bubbles‚ I ruled out Streptococcus lactis. My organism did have the catalase enzyme; meaning it was either Bacillus subtilis or Staphylococcus. To distinguish the two‚ I performed the simmons citrate test on them. Since the tube stayed green I confirmed that my organism was Staphylococcus. My organism B could not degrade citrate‚ so that meant my organism was not Bacillus subtilis. In conclusion‚ my unknown organisms were Staphylococcus and Enterobacter aerogenes. REFERENCES Kidane‚
